In our study, we tried to develop and test a model that aids further understanding of the sources of customer loyalty in the 3G telecommunications service. In addition, as the 3G could be understood as an innovative telecommunications service, we assume that the impact of factors related service attributes affecting customer loyalty is moderated by the customer's innovativeness. We analyzed our research model using 3G service users' data in Korea. Our results will have significant strategic implications for firms in this highly competitive industry. Particularly, it can be useful for mobile carriers interested in customer retention management and supposed to deliver a new telecommunications service like the 4G service that is on the horizon.

Although the telecommunications service industry has become a basic infrastructure component of the information and communication technology (ICT) industry, it is now losing its reputation as a cash cow due to achieving a saturation of service subscribers, especially in South Korea. With the exception of improving network speeds, network operators are experiencing difficulties in creating new innovations. Therefore, new innovations for the telecommunications service industry should be identified in conjunction with government policies for industry promotion. To examine the innovative capabilities of a specific industry, innovation system theories were used as a framework for research. However, existing innovation systems are limited with regard to explaining the openness of relationships and user participation which are general properties of the ICT industry. Moreover, as sources of innovative activity, additional values such as financial support and collaboration are more appropriate. This study presents a new innovation system based on innovation values. We analyze the telecommunications service industry and prioritize the importance of telecommunication policies within South Korea. An in-depth interview with experts based on the innovation system framework is conducted first. Next, innovation factors derived from the interview are applied within an analytic hierarchy process (AHP), leading to a prioritization of innovation factors for the telecommunications service industry.

Terrestrial digital multimedia broadcasting(T-DMB) is one of mobile broadcasting services, and the commercial service was started in December 2005 in Korea. The performance targets of T-DMB are providing VCD(video CD) quality video and FM radio quality audio. In recent years, the researches for providing high quality video or audio service on T-DMB environments have been being carried out. To provide high-quality video or audio service, some additional data should be transmitted to the receiver as well as T-DMB video and audio data. Since the data rate for one T-DMB program is low, it is important to transmit the additional data at a low bit rate. In this paper, we propose a packetizing method for efficient transmission of the additional data to provide multichannel audio service on T-DMB environment.

This paper proposes a kind of function-concentrated signaling service equipment structure, in which various kind of signaling service are efficiently made for call processing control. Based upon the typical switching system models, a philosophical study on the capacity, features of structure in world systems, and interfaces with peripheral equipments has been performed in order to provide the rationale on the merits or efficiency of the proposed digital signaling service equipment.

This paper introduces a novel repetitive delivery scheme for the left and right views in service-compatible (SC) 3D video that provides full backward compatibility to a legacy DTV system while retaining HD 3D visual quality without additional bandwidth or a codec over the legacy broadcasting channel. The proposed SC delivery scheme transmits individual view sequences of a 3D video in interlaced form, that is, a left-view sequence of a 3DTV program to be used repeatedly is transmitted first and stored locally, and the right-view sequence of the 3D program is then transmitted. This paper specifically describes the signaling, synchronization, and storage format methods used to validate the proposed SC delivery scheme. The experiment results show that the proposed SC delivery scheme can be effectively applied for an SC 3DTV service without degrading the DTV quality using only legacy DTV platforms.

This paper discusses service discoveries for smart trusted reality (TR) glass and networks developed by the Electronics and Telecommunications Research Institute. TR glass provides a differentiated gaze communication service from the well-known AR glass. Services include on-off of products that reach the eye, encryption of courier addresses, and time-based networking services. This paper addresses the technical roots and service scalability of TR glass. Furthermore, the agricultural sector was selected to provide microservices configuration, connectivity with 5G communication, and a full range of applications for extended services.

This paper was studied on influence analysis of Telecommunications Network in Electronic Government. Analysis method was studied of Policy Delphi. The five kinds of telecommunications network influence in Electronic Government is National Information Infrastructure Networt, Local Area Network, Integrated Services Digital Network Public Switched Telephone Network, and Cable TV Network. The five kinds of telecommunications network service influence in Electronic Government is Telecommuting Service, Internet Service, PC Telecommunications Networt Video Conference Service and Electronic Data Interchange Service. The five kinds of telecommunications influence in Electronic Government is as follow: First Telecommuting Service must be Constructed. Second, Public Administration Service must be improved. Third. citizen must be participated in decision making. Fourth, Public Administration duty service must be digitalizing. Fifth, Video Conference Service must be improved.

Consumer needs becomes various in a mature mobile telecommunication market, while service differentiation is hard to achieve. The competition among telecommunication service providers is getting fierce in order to maintain and obtain customers. Moreover, HSDPA caused the intense marketing activity for the move to the next generation customers. Under these circumstances, brand equity can be a key to a long-term competitive edge for mobile phone service providers. In this study, we identified the factors influencing mobile telecommunication brand equity, and its influence on the HSDPA service subscription behavior.
